WOODWORKINGHVIACHINE.

SPECIFICATION forming part of Letters Patent No. 689,027, dated December 17, 1901.

' Application filed October 13, 1898. Serial No. 693,417. (No model) To 60M w/wm it may concern.-

Be it known that I, ROBERT SCHLEICHER, a

citizen of the United States, residing at Louisville, in the county of Jefferson and State of 5 Kentucky,have invented certain new and use-' fulImprovements in Woodworking-Machines,

of which the following is a specification.

My present invention pertains to improvements in machines for dressing lumber, the

construction and advantages of which will be hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the machine;

Fig. 2, a top plan view; Fig. 3, an enlarged I 5 perspective view of certain of the operative machine which will take a strip having its two wide faces dressed, but with its edges or sides in the rough, and dress said sides sim ul-.

taneously, at the same time forming a rabbet in one face of the material.

Referring to the drawings, A indicates the base of the machine, and B thehorizontal table mounted thereon. At one end of the table there is placed an adjustable hopper or holder comprising the side walls or faces 0,

provided with vertical arms D at their forward ends, said arms, as will be seen upon reference to Fig. 2, being provided with a shoulder E to prevent the strips whichare placed within the holder or chute from being 40 fed forward except at the bottom or next to the bed-plate, where the arms are cut away to permit one strip to be fed forward upon the table.

As will be seen upon reference to Figs. 2

and 3, the side walls or members 0 of the from the members 0.

Suitably journaled upon the bed directly in front of the arms D of the chute and at a slight distance therefrom is a shaft H, having mounted upon it cutter-heads Lprovided with suitable blades which are designed to act upon the edges of the strip which passes out between them from the chute or hopper. These cutter-heads may be adjusted back and forward upon the shaft H to accommodate any width of strip desired.

To feed the lowermost strip forward between the cutters I and out at the bottom of the chute, I employ a feed-chain J, having teeth K. The chain J passes about asprocketwheel L at the head of the machine, over the bed-plate B, in between the side walls of the chute along the bed-p1ate nearly to the oppo site end of the bed, where it passes down through an opening around a sprocket-wheel M, mounted upon a shaft N, and thence around an idler O, adjustably mounted upon the base of the machine. By means of the idler O proper tension can be had upon the driving-chain.

P denotes a cutter designed to extend up through the bed of the table and preferably below the shaft H between the cutter-heads I. This cutter P forms the rabbet Q, Fig. 5, in the lower face of the strip.

To properly guide the strips as they pass out of the hopper or chute, I provide suitable abutments or guards R and S, which, like the hopper-walls, are adjustable toward and from each other. Guard S extends up quite a distance above the face of the bed and is provided with yokes T, in which are mounted rolls U, held down upon the work by springs V. One of these rolls Uoccupies a position between the uprights D of the chute and the crossshaft II and securely holds the end of the strip down upon the bedplate as it passes out of the chute, thereby insuring the cutting of the rabbet to the full depth at the beginning of the operation. There is also mounted in the guard S a rod or shaft W, which may be adjusted lengthwise and held in its adjusted position by a bolt X. Extending through the head of said rod or shaft is a spring-arm Y, carrying at its lower end a roll Z, the arm Y being adjustable through the head of the rod or stem and held in its adjusted position by a bolt Ct. The distance between the bearing-point of the rollZ and that of the roll U nearest thereto is decated by the reference-letter b, and extending from a pulley mounted thereon is adriving-belt c, which passes around a smaller pulley mounted upon the shaft upon which the cutter P is secured. A second belt 01 passes around a pulley e, mounted upon the shaft b, and imparts motion to the shaft H, as indicated in Figs. 1 and 2. Athird beltfextends from a small pulley h upon shaftb around a larger pulley 2', which is mounted upon a shaft j. Upon said shaft there is secured a relatively small sprocket 7c, and from said sprocket motion is imparted by a sprocket-chain Z to a large sprocket m, secured upon the shaft N.

From the connections just described it will be seen that a relatively high speed is imparted to the cutter-heads I and the rabbeting-cutter P, while a slow motion is imparted to the carrier-chain J.

In the operation of the machine the strips, such as indicated in Fig. 4:, having their flat faces dressed, but with the edges rough, are placed or piled one upon another in the chute or hopper at the head of the machine, the forward ends of the strips bearing against the shoulder E of the uprights D. Motion is then imparted to the mechanism, when the feedchain J will engage the lowermost strip and feed the same forward beneath the first roll U, over the rabbet-cutter P, and in between the edge-trimmers or cutter-heads I. The rabbet Q, will be formed as indicated in Fig. 5, and the edges of the strip will also be dressed. As the first strip passes out of the chute or hopper the feed-chain will engage the next, which is forced downward by the weight of the blanks above, and the operation will continue so long as motion is imparted to the mechanism. The strips thus prepared are especially designed for making up boxes, more particularly boxes for packing tobacco, wherein it is absolutely essential that the parts or sides should be finished to a nicety in order that they may come together so close as to present a substantially moisture-tight joint. The machine has been employed for making strips for boxes of this character and has been found to work to advantage.

Having thus described my invention, what I claim is 1. In a woodworking-machine; the combination of a base; a bed-plate mounted thereon; a hopper located at one end of the bedplate and provided with adjustable side walls 0 and shouldered uprights D; a shaft H journaled upon the bed-plate adjacent to said chute or hopper; rotary cutter-heads I mounted upon said shaft, said cutters being provided with cutting-blades to act upon the edges of the blanks; a rabbeting-cutter P having its upper edge extending slightly above the upper face of the bed-plate; guides R and S mounted upon the bed-plate; presser-rolls V; and means for feeding the blanks forward from the hopper.

2. In a woodworking-machine, the combination of a base and a bed-plate mounted thereon; a hopper located at one end thereof; shaft H journaled upon the bed-plate adjacent to the hopper; face cutter-heads I adjustably mounted upon said shaft; a rabbeting-cutter P having its upper edge extending slightly above the upper face of the bed-plate; guides for the blanks to be operated upon; means for feeding the blanks forward; presser-rolls-U; and a presser-roll Z located at the tail end of the machine acting toward the bed thereof, substantially as and for the purpose described.
